Hi Peer , as talked to Gordon, this was a total upgrade from 2.0.x to
2.1.x and you converted all maildir to compressed before, right ?
posting some conf parameters might be helpfull , did you investigated
broken maildirs for mixing compressed and uncompressed mails exist, as i
understand Gordon there should be only compressed ? Have you checked
about double compressed mails in broken maildirs ?

As wrote before, at my bug time after repair with script and upgrading
dovecot, failures had gone and never returned, but my setup may be
different from yours and failure did happend sometime upgrade dove 2.1.x
not at migrate from dove 2.0.x, did you changed something other too ?

Best Regards
MfG Robert Schetterer
